wpf datagridcheckboxcolumn style

Question

Imagine I have a CheckBox custom style named "MyCheckBoxStyle".

How can I make a Datagrid style that embeds a custom DataGridCheckBoxColumn style based on my MyCheckBoxStyle?

Solution 1

You can use DataGridTemplateColumn to create a custom checkboxcolumn

                                <Custom:DataGridTemplateColumn x:Name="gdchk" Header="Test" MaxWidth="50">
                                <Custom:DataGridTemplateColumn.CellTemplate >
                                    <DataTemplate>
                                        <CheckBox IsChecked="{Binding Path = classname}" HorizontalAlignment="Center" Style="{DynamicResource myCheckBoxStyle}"/>
                                    </DataTemplate>
                                </Custom:DataGridTemplateColumn.CellTemplate>
                            </Custom:DataGridTemplateColumn>

Hope this helps.

You can simply use your defined style with ElementStyle attribute.

Style defined in resources:

<Style x:Key="MyCheckBoxStyle" TargetType="{x:Type CheckBox}"> ... </Style>

And my datagrid checkbox column:

<DataGridCheckBoxColumn ElementStyle="{StaticResource MyCheckBoxStyle}" Binding="{Binding someValue}" />

try this

<DataGridCheckBoxColumn MinWidth="100"
               Binding="{Binding Path=BoolValue}"
               Header="Bool Column"
               IsThreeState="True">
                <DataGridCheckBoxColumn.ElementStyle>
                    <Style TargetType="CheckBox">
                        <Setter Property="Background" Value="{Binding BoolValueColour, Converter={StaticResource MyConverter}}" />    
                    </Style>
                </DataGridCheckBoxColumn.ElementStyle>
 </DataGridCheckBoxColumn>
